[PATCH 1/3] ASoC: cs42l42: Correct definition of ADC Volume control
The ADC volume is a signed 8-bit number with range -97 to +12, with -97 being mute. Use a SOC_SINGLE_S8_TLV() to define this and fix the DECLARE_TLV_DB_SCALE() to have the correct start and mute flag.

The driver has no support for left-justified protocol so it should not have been allowing this to be passed to cs42l42_set_dai_fmt().

An I2S frame always has a left and right channel slot even if mono data is being sent. So if channels==1 the actual bitclock frequency is 2 * snd_soc_params_to_bclk(params).

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

Ugh, sorry - the script is confused. This is applied to the ASoC tree.
